The paper reviews both the influencing factors and calculation strategies of sample size
determination for survey research. It indicate the factors that affect the sample size determination …

This paper introduces a SAS/IML program to select among the multivariate model candidates
based on a few well-known multivariate model selection criteria. Stepwise regression and …

A study was conducted to compare the response rate of telephone interview and Web Survey
in Saudi Arabia utilizing Internet usage statistics, as well as experimental design. Official …

In this paper a new test statistic is developed to evaluate model specification for nonnested

A modification of the Kaiser and Dichman (1962) procedure of generating multivariate random
numbers with specified intercorrelation is proposed. The procedure works with positive …

A Monte Carlo study was used to compare the Type I error rates and power of two nonparametric
tests against the F test for the single-factor repeated measures model. The performance …

Most multivariate statistical techniques rely on the assumption of multivariate normality. The
effects of nonnormality on multivariate tests are assumed to be negligible when variance–…

A Simulation study was conducted, to compare a number of univariate variable selection
criteria that are available in either SAS or SPSS, in terms of their ability to select the “true” …

Applications in which several quantities are to be predicted using a common set of predictor
variables are becoming increasingly important in various disciplines. However, three …

The location of Fallujah, sitting on land and river transport routes, coupled with its proximity
